" FIXING DEVICE FOR CLOSING DOORS OR WINDOWS "

DESCRIPTIVE MEMORY

BACKGROUND OF THE INVENTION The present invention relates to a fastening device for door or window closure, constituted by a sliding part (1), wherein the catch (2) is mounted, which when subjected to the axial action of a spring (4) , moves guidedly through the interior of the closure embossing body or body (3). The present invention relates to a fastening device for closing a door or a window, and is generally intended for fastening metal window frames, and in particular for door and window latches with sliding shoulders.

In the current state of the constructive technique relating to closures applicable to doors and / or sliding windows, a type of closure is known which comprises a box-shaped embedding body, inside which is housed a part with a certain profile which presents the tongue and which, when subjected to the axial action of a retrieval spring, is able to move longitudinally either by manual action or by action on the door frame, in order to cause engagement of the pawl in the closed position, effecting thus closing the door and / or window.

Likewise, in the technique applicable to door and / or metal window latches, it is also known that the sliding or sliding piece, to which the bolt is associated, can be fixed in the closed position and ensure the locking of the bolt on the slide until it is desired to open the door voluntarily, it being necessary for such to unlock the slide part which can then slide freely by the action of its retrieval spring, thus enabling the unlocking of the pawl and hence the opening of the door.

There are a variety of types of fasteners with fastening, among which it is desirable to emphasize, by virtue of their good results, a fastener composed of a box-shaped slide which is housed in a sector or zone of the closure box, projecting into one of ends of the carton in order to function as an impeller which, upon being actuated, acts during its displacement on an eccentric engaging the sliding part, which is locked in the closing position of the door, being able to be released when it is actuated a button which raises the eccentric, thus releasing the slide part which will move freely by action of its recovery spring to the opening position of the catch.

This type of fasteners have the disadvantage of being made up of a series of pieces with a more or less complex configuration, which require an independent manufacture with a special modeling, as well as later assembly that must be executed by specialized labor, which increases the manufacturing costs of the product.

In order to avoid these drawbacks, the present invention has studied and perfected a fastening device for door and window fasteners, the new simplified structure of which not only eliminates unnecessary parts in its manufacture but also a simple assembly of its elements, leading to economy of time and power, which favors the serial production of fasteners at reduced costs.

To this end the invention is based on a closure which is constituted by a special part with a certain profile, on which the catch bolt is mounted, which part is mounted inside the body or enclosure embellishing the closure and can move or slide by axial action of a recovery spring, in this movement being guided longitudinally by said housing, during which said displacement takes place the engagement or disengagement of the catch of the catch in the slide. The invention is characterized in that the slide or moveable part inside the box has, in the region close to the

a thicker end, a lateral or transverse bevel, provided for receiving, with the interposition of a recovery spring, an independent part constituting the button or impeller. Said part or impeller has a special configuration for engaging the slide bevel, essentially consisting of a lower projection or appendage which protrudes with respect to the slide so as to be guided by the edges of a longitudinal groove provided in the housing or body embellisher of the clasp.

In the displacement of the slide, the protrusion of the impeller is guided by the groove of the carton until the slide reaches its end closure position and, at that instant, the impeller is released from the guide and moves by its internal spring to its flush with the edge of the housing groove. The fact that the impeller protrusion abuts with the edge of the groove of the carton prevents the sliding member from moving, although it is subjected to the tension of its recoil spring which is compressed, thereby locking its movement, as well as that of the which tongue, in the closed position, will engage the slide.

When it is desired to unlock the catch and thus the slide, it will suffice to push the button down until its protrusion ceases to be top with the edge of the groove, thus being possible to release the slide, which will be driven by its spring of recovery to the opposite position corresponding to the opening of the catch, the protrusion of the impeller being in said sliding movement of the slide guided by the longitudinal groove of the carton.

From the foregoing disclosure it will be seen that the device for securing a door or window fastener which forms the object of the invention has the following advantages: a. To improve the design of a closure intended for metal frames by providing it with an unconstrained fastening device which enables it to eliminate unnecessary parts from its manufacture. B. To facilitate the assembly of the closure elements, which are all coupled to the profile constituting the slide, which is easily mounted within the closure body without the need for specialized manpower. W. To improve the operation of a door or slide window lock, the simple actuation of which on the impeller associated with the slide enables it to unlock its movement and is moved to the opening position of the catch. d. Simplicity of organization and placement of fastener elements with fastening system, which allows easy production in series with reduced manufacturing costs.

For a better understanding of the foregoing, the present specification is accompanied by a set of drawings wherein the object of the invention can be seen, it being understood that the graphic representation referred to does not constitute a limitation of the peculiar characteristics of this application.

Figure 1 - Represents a view of a longitudinal section of the closure. In it it can be seen that the slide in which the catch bolt is mounted is moved to the opening position of the catch by the action of its axial spring which is distended. The slide attachment button or impeller is housed in the thicker end of the profile, having a lower appendage or protrusion which is guided by a groove in the housing or closure embedding body.

Figure 2 - Represents the same longitudinal section of the anterior view but in the closed position. In it it can be seen that the slide has moved to the opposite end of the catch, compressing its recovery spring. The clamping impeller moving with the slide has overcome the guide of the carton and due to the distension of its internal spring its lower projection or appendage is top with the edge of the slot of the carton, thus preventing the displacement of the slide , the tongue of which is unmovable in the closed position.

Figure 3 - Represents a cross-section of the closure in the region of the securing impeller. In it it can be seen that the impeller is an independent part housed in a chamfer or lateral groove of the thicker end of the profile constituting the slide, being provided with a lower flange in the shape of " T " which is guided by a groove in the carton or catch body. Said groove or groove of the profile has a small lower flap where it supports a recovery spring, which is mounted in a blind cavity of the impeller.

After the detailed description of the figures forming the set of drawings, reference will now be made to the various elements which form the object of the invention. The closure is constituted by a part with a certain profile (1) or slide, with a catch tongue (2) being mounted at one of the ends which is fixed by means of a threaded stud. Said sliding member is normally mounted to a bevelling body or housing (3) of the catch, which, when subjected to the axial action of a retrieval spring (4), moves or slides along said housing, at the same time as it is guided by it during this movement. The sliding or sliding part through the interior of the carton has a lateral or transverse bevel at its thickest end 5, where a part constituting a button or impeller 6 is housed. Said part or impeller has a special configuration for engaging the slide bevel and is principally comprised of a tail-like lower appendage (7) which protrudes with respect to the slide so as to be guided by the edges of a longitudinal groove (8) provided in the closure embossing body or housing. The button is subjected to the action of an internal spring (9), which is mounted in a blind cavity of the button, while its opposite end rests on a small flap (10) provided in the lateral notch of the slide.

The entire assembly is arranged in such a way that in the displacement of the slide (1), which can be obtained by manual actuation on said slide or by action of the pawl (2) on the frame or slide of the door or window, the impeller 6) moves with the slide, its projection (7) being guided by the longitudinal groove (8) of the carton (3).

When the slide 1 reaches its maximum closing position, the impeller 6 is released from the guide 8, its inner spring 9 can then be distended and, with this movement, Said impeller until its protrusion (7) is top with the front part of the groove of the carton. The protrusion 7 of the impeller 6, when abutting with the edge of the groove of the carton, prevents the slide 1 from moving despite being subjected to the tension of its recovery spring 4 which is thereby preventing the movement of said slide part, and also that of the catch (2) which, in its closed position, will be imbedded with the slide.

In order to unlock the catch and thus the slide (1), it is enough to push the knob (6), thus compressing the spring (9), whereby its projection (7) will no longer be top with the front of the (8), whereby it is possible to release the slide.

Upon release of the impeller protrusion, the slide (1) will be pushed by its recovery spring (4) to the opposite end of the carton corresponding to the opening of the closure, the protrusion (7) of the impeller, in said displacement of the slide , guided again by the longitudinal groove (8) of the carton.
